摘　　要：目的 探讨经阴道彩色多普勒超声对子宫颈癌诊断的意义.方法 选取子宫颈癌可疑患者45例于术前行TV-CDU检查,二维超声检查记录其形态特点,后经阴道彩色多普勒超声检测肿瘤内的血流情况,测其阻力指数(RI).结果 45例子宫颈癌患者可探及血流信号(RI值为0.51±0.09),与正常子宫颈上皮(RI值为0.82±0.06)相比差异有统计学意义(t=18.714,P<0.001),RI值与子宫颈癌的癌灶直径、临床分期、病理分级、淋巴转移有关(P<0.05),与患者年龄、病理类型无关(P>0.05).结论 RI反映子宫颈癌的血管生成特征.并且与子宫颈癌的临床病理参数之间有一定的内在联系.经阴道彩色多普勒超声术前较准确地预测子宫颈癌内血管生成,可作为子宫颈癌诊断的重要辅助手段之一.为其预后评估标准提供依据.Objective To explore the significance of transvaginal color Doppler ultrasound in the diagnosis of cervical carcinoma. Methods 45 patients undergoing surgery for cervical carcinoma were enrolled. Transvaginal color Doppler flow imaging was performed preoperatively to detect the arterial blood flow signals within the tumors and the lowest resistance index (RI) value was recorded for analysis. Results Significant difference RI values were noted in cervical carcinoma group compared with contrast group (P <0.001). RI were associated with tumor diameter, stage status, pathologic grade and pelvic lymph node metastasis of cervical carcinoma(P < 0.05). There were no relations between RI and patients's age and pathologic type (P >0.05). Conclusion The angiogenesis character of cervical carcinoma can be showed by RI, and RI had some inherent connections with clinicopathologic parameters of cervical carcinoma. Transvaginal color doppler ultrasound could accurately predict angiogenesis of cervical carcinoma preoperatively and be of importance in the diagnosis of cervical carcinoma. It could provide standard in prognosis evaluation.
